Nah, the kid’s right. Suppose Marty eats 4/6 of his pizza p1, and Luis eats 5/6 of his pizza p2, it means that for 4/6 p1 > 5/6 p2, p1 > (5/6)/(4/6) p2, which equals p1 > 5/4 p2
In other words, Marty’s pizza needs to be at least 25% larger than Luis’.
That teacher should be fired How can they be allowed to teach and fuck that up
90% of these are faked for Internet points. Just like 99% of text message screenshots.

This is one of those problems that makes more sense with context. The teacher had the students working on “reasonableness”, which is essentially “does the question I’m asking make sense?”. The students were probably instructed to ignore actually trying to solve the problem when presented with one, but instead explain why the question either does or doesn’t make sense.
In this case the student potentially misunderstood the task. The failure on the teacher’s part is wording the question in such a way that it actually has a reasonable solution, and isn’t necessarily an unreasonable question.
This isn’t testing reasonableness. This is testing to see if a student understands that to properly compare fractions the wholes have to start as equivalent.
Source: I use questions similar to this every year because if I don’t get some real funky diagrams.
Sorry I’m still trying to get my head around the question. What is the answer the teacher expected/ the question the teacher meant to ask? 🤔
It makes more sense when you remove the fractions, but I assume they were working on them.
It’s easier this way: “John ate 4 slices of pizza. Dave ate 5 slices of pizza. John ate more slices of pizza than Dave. How is this possible?”
The answer they’re looking for is: “This is not possible because 5 slices of pizza is more than 4 slices of pizza.”
It’s a really bizarre question, and is poorly worded, but the concept could be really important depending on the age/ability of the student.
It’s like teaching a kid to fact check I guess.
is this common core?
if so its is teaching how unreasonable the world can be at least.
